I'm not outright disagreeing with you, donny2112, but I am getting a very sustaining-technology feeling from this line of argument. It feels like that moment right before an established market leader is utterly destroyed by a disruptive technology. The management for the leader keeps focused like a laser on profitable technology streams right up until the moment when the world shifts and they simply aren't anymore.
I think it's a decent bet that the existing market will be disrupted by a company making a handheld and console in one. Like what Microsoft is going to do next year, I suppose. Or what Sony could have done if they'd used the game streaming tech to make their handheld market something Nintendo and Microsoft and Apple and Google could only dream of.
Or, more likely, what Apple could do if it wanted to.
That is, Nintendo may not be able to survive by combining console and handheld in one, but the company that leads the market next could succeed by doing so from below.
You're making the same mistake others make of analyzing the Gaming industry as a tech industry and not the entertainment industry it is.
